実験手順: 3-Hydroxybenzaldehyde (3.0 g, 24.6 mmol), ethyl iodide (5.9 ml, 73.8 mmol) and K2CO3 (3.4 g, 24.6 mmol) in 50 ml of acetone was stirred at +40° C. for 6 h and at RT overnight. The mixture was filtered and evaporated. The product was purified by silica gel column chromatography (EtOAc/petroleum ether 15:100) to give 3-ethoxybenzaldehyde. The mixture was filtered evaporated The product was purified by silica gel column chromatography (EtOAc/petroleum ether 15:100)

実験手順: Prepared according to the described general procedure 2 (GP2) by reaction of ethyl 4-amino-4-(2-ethoxy-6-fluorophenyl)-2-methylbutanoate with commercially available 3-ethoxybenzaldehyde. Subsequent purification by preparative HPLC afforded the target compound. LC-MS (conditions A): tR=0.92 min.; [M+H]+: 372.03 g/mol. Prepared Subsequent purification by preparative HPLC afforded the target compound
